Abstract
A progressive die process for making medical needles attached to a carrier strip, as well as the product of the process. The process includes steps of forming a flat blank in unitary attachment with a carrier strip and coining edges of the tip of each flat blank, arcuately shaping the blank, and closeably forming the arcuate blank to create a medical needle having a holding portion, a cannulated portion and a tip. In addition, the cannulated portion may be encased for fluid delivery or grooved so the needle may be split.
Claims4
A method for manufacturing from a roll of sheet metal medical needles unitarily attached to a carrier strip, each of said medical needles being longitudinally oriented with proximal and distal ends, each of said medical needles having a tip at the distal end, a holding portion at the proximal end, and a cannulated portion between said tip and said holding portion, said holding portion being attached to said carrier strip, said cannulated portion having opposite longitudinal edges, said method comprising the steps of:
- forming a flat blank in unitary attachment with said carrier strip and coining edges of said tip;
- forming with a set of first dies said blank into an arcuate shape;
- and
- closeably forming with a set of second dies said arcuately shaped blank to form said holding portion, said cannulated portion and said tip, said blank being shaped so that said opposite edges of said cannulated portion are moved into facing proximity with one another.
